Arctic Ice Vanishes Over 30 Years

A chilling NASA simulation shows how it happened.

In this video, NASA visualizes its Arctic sea ice data from 1984 to 2016, and the result is dramatic. And scary.

The ice has been disappearing since 1984 because of global warming. This “perennial ice”—about double the thickness of seasonal ice—is the most critically important ice cover for the Arctic. It’s vital to the survival of native Arctic animals and people, of course, but it also plays a key role in moderating the entire planet’s climate. And there’s barely any of it left.
